sanity check, 2 ndmpd sessions @ once? - toasters

13 Feb 2003


      Noticed this on a 740 that's only got 1 DLT.
Veritas netbackup is scheduling bkp jobs with ndmp,
from a sun box.  There've been some odd failures where
the tape fails to unload after the bkp, recently.  ndmpd
status doesn't show any sessions active when that happens 
though.  Right now I'm seeing 2 ndmp sessions; I don't
recall that before, and I'm wondering if this means 
netbackup is having problems.  The ip addr is the sun
box running nb, for both sessions; there's a bkp running
while I'm looking at this.  6.1.3R2
